Expert take: what JNCIS-ENT really tests
JNCIS-ENT is Juniper’s specialist enterprise routing-and-switching exam — 65 questions in 90 minutes — and it requires the JNCIA-Junos associate cert first. It is hands-on and CLI-oriented, so configuring OSPF, BGP, VLANs and routing policy on Junos is the most effective preparation.
Preparation tips
- Hold JNCIA-Junos first — it is a prerequisite.
- Practise Junos CLI: OSPF, BGP, VLANs, spanning tree and routing policy.
- Study the official objectives and recommended courses (JIR, JEX).
Common mistakes to avoid
- Studying concepts without Junos hands-on configuration.
- Neglecting routing policy and firewall filters, distinctive Junos topics.

Sample JNCIS-ENT practice questions
5 questions taken from the JNCIS-ENT mock tests on Wrexa Edge. Try each one, then reveal the answer.
-
Q1. Why does iBGP traditionally require a full mesh of sessions?
- iBGP peers prepend their AS number before advertising to iBGP peers
- iBGP sessions require directly connected interfaces between all peers
- iBGP routes are installed only when learned from two separate peers
- iBGP peers do not re-advertise iBGP-learned routes to other iBGP peers
Show answer
Answer: D — iBGP peers do not re-advertise iBGP-learned routes to other iBGP peers
The iBGP split-horizon rule prevents loops inside an AS; route reflectors or confederations relax the full-mesh requirement.
-
Q2. Which command validates the candidate configuration syntax and semantics without activating it?
- commit check
- show | compare
- commit confirmed
- validate candidate
Show answer
Answer: A — commit check
commit check runs the full commit validation (including commit scripts) but does not apply the candidate configuration.
-
Q3. An area must block Type 5 LSAs but still allow an ASBR inside it to import static routes. Which area type fits?
- Stub area
- Not-so-stubby area (NSSA)
- Totally stubby area
- Backbone area
Show answer
Answer: B — Not-so-stubby area (NSSA)
NSSA blocks Type 5 LSAs but lets local ASBRs originate Type 7 LSAs, which the ABR translates to Type 5 for the backbone.
-
Q4. Which RSTP port role provides an alternate path to the root bridge and becomes root port quickly if the current root port fails?
- Backup port
- Designated port
- Alternate port
- Edge port
Show answer
Answer: C — Alternate port
An alternate port receives superior BPDUs from another bridge; a backup port is a redundant link to the same segment as a designated port.
-
Q5. Which statement best describes how Junos evaluates a routing policy with several terms?
- Terms are checked in parallel and the most specific term wins
- Terms are checked in order and every matching term is applied in turn
- Terms are checked by their numeric names from lowest to highest
- Terms are checked in order until a terminating action is matched
Show answer
Answer: D — Terms are checked in order until a terminating action is matched
Policy terms are evaluated sequentially; accept or reject ends evaluation. If no term terminates, the next policy in the chain, then the default policy, is used.
